The big problems with others reproducing this are:
1) My diode reader is not of the DIY variety, but instead is the full package from Maxim on pcb connected to the parallel port of a second PC. This gives me the "extra bits" from the 6655 for 0.125C resolution. Not many will want to drop $100US for the package (though it is a very nicely made setup).
2) When you turn the CPU over and get out the soldering iron, you tend to lose your nerve. If you get the pins too hot, you will kill the diode. If you get the core itself too hot, you'll kill the chip. Your iron may not be grounded and so ESD is a concern as well. Not to mention, it is pretty ****ing insane to just start soldering copper wire to the CPU. To top it all off, when you are done then you have to hack up the top part of the socket to make room for the wires.
I can't really see anyone else doing something like this. The whole time I was getting the nerve to do it, I was thinking about how STUPID an idea that it was.
